Nemotron 3 Ultra is a 550-billion-parameter open model that NVIDIA claims is the highest-performing open model from an American company. Benchmark comparisons against Chinese open models GLM 5.1, Kimi K2.6, and Qwen3.5 show Nemotron 3 Ultra winning in multiple tests and offering superior cost efficiency. However, on the Artificial Analysis Intelligence Index, Nemotron 3 Ultra scored 48 points, below Kimi K2.6's 54 points. NVIDIA emphasized Nemotron 3 Ultra's processing speed advantage, showing it can output more tokens per second than models in its score range. The model is scheduled for release within the first week of June 2026. The Vera Rubin server combines the Rubin GPU and Vera CPU with dedicated storage and networking, targeting agentic AI workloads. Huang also announced the RTX Spark SoC for notebook PCs and the DGX Station desktop PC.","whyItMatters":"Nemotron 3 Ultra positions NVIDIA as a contender in the open model space against rapidly improving Chinese models, but benchmark results show it trails the top Chinese open model in raw intelligence while leading in throughput.","webCardHtml":"\u003cp\u003eNVIDIA CEO Jensen Huang made the announcements during the GTC Taipei 2026 keynote on June 1. The event was held at 12:00 JST. Alongside Nemotron 3 Ultra and Vera Rubin, Huang announced the RTX Spark SoC for notebook PCs and the DGX Station desktop PC.\u003c/p\u003e\n\n\u003cp\u003eThe RTX Spark combines an Arm-based CPU, an NVIDIA Blackwell RTX GPU, and up to 128GB of unified memory with full CUDA support. It dynamically allocates memory to improve efficiency for heavy workloads such as simultaneous AI generation, 3D rendering, and multi-model workflows. The chip can run AI models with up to 120 billion parameters locally.\u003c/p\u003e\n\n\u003cp\u003eMicrosoft announced on May 31 the Surface Laptop Ultra, a notebook PC that adopts the RTX Spark. The Surface Laptop Ultra targets AI developers and creators and is scheduled for release in the latter half of 2026. It has a 15-inch touch-enabled mini LED display, a haptic feedback touchpad, and ports including HDMI, USB-C, USB-A, and a full-size SD card slot. Colors are Platinum and Nightfall.
